Cryptography confusion and diffusion

WebFeb 15, 2024 · Due to the strong correlation between adjacent pixels, most image encryption schemes perform multiple rounds of confusion and diffusion to protect the image against attacks. Such operations, however, are time-consuming, cannot meet the real-time requirements of video encryption. Existing works, therefore, realize video encryption by … WebCommunication", confusion and diffusion are two properties necessitated for the operation of any secure cryptographic algorithm [1]. In the classic ciphers these attributes were achieved by the use of substitution or transposition ciphers. Modern cryptography utilizes the same phenomenon in the form of substitution-permutation network (SPN).
